To all @i1/omit may concern.'

' Be it known that ive, PHILIPPE l/VERNER ERNEST JUILLARD, citizens of the Conresiding in Chtelane, neai' Geneva, Canton ot Geneva, in the Confederation of Switzerland, have jointly invented an Improvement in Automatic Electric Regulators, of which the following is a specification.

The subject of the present invention is an which is provided with a rotary slide valve of which apart forms aditferential piston,

upon the surfaces of which acts in onel direction a liquid which is under pressure and 1n the other direct-ion a liquid which can one or more openings which '5 .are controlled by a light controlling device which moves with the member which is under the influence of the quantity to be regulated, for the purpose of reducing as much as possible the mass which has to be moved by the first member in order to actuate the regulator.

Moreover, our invention includes apparatus for preventing overregulating. and this apparatus preferably consists of two laminae, the corresponding ends 'of which ,are fixed in position. The other end. of one lamina. is connected by means of an adjustable device with the regulating member While t-lie other end of the other lamina is i connected with the member which is under the influence of the quantity to be regulated. The laminas are connected between their endsby means of a link, the position of which may be varied, in order that simultaneouslyY with the regulation of the adjustable device, the tlirottling of the regulating oscillations may be regulated until there is a complete suppression `oit these oscillations.

The accompanying drawing shows by Way of example a ccnstructional form of the regulator according to the present invention.

Figures 1 and 2 illustrate together a cross section and Figs. 3 and 4 a partial longiy itudinal section of this constructional form;

I' Figm is an elevation ot the y3. Fig. 6 is a side elevation of the laminae Aand associated parts. Figs. 7, 8, 9, 10 and electromagnet l1 are .sectional views through the lines governor age of an electric central installation and 1 for the purpose is provided on one side with a coil .1 (Fig. 3) which is movable between the limbs 2 of a ythree-pole electromagnet 3, as shown inlfig.v 5, the coil being controlled by the systen'ito-be regulated, that is, by the voltage of the installation; on the other side the regulator is provided With a regulating mechanism in the form o :t a rotary contact arm 4, Fig. 2, right 'hand side, whichy is adapted to connect a fixed contact ring 5 with a series ofv fixed contacts 6. p Q,

The coil 1 is liXed atene end of the lever 7, the movements of which are limited by stops 7 and the other end of which carries the controlling` membeigfa rod 8, Fig. 1, with a sleeve 8. This member actuates the slide valve 9,' throttling more or less the passage of a liquid such as oil, which is set under pressure by a pump 1(7), whereby the slide valve allows the liquid under pressure to fioiv into the. one or other of tivo chambers of the driving apparatus 11, which are partly separated by a rotary plate 12,.\vhicli is connected with the contact arm 4, and whereby said ar'ni is moved in one direction or the other.`

The pump 10,-Figs. fl and l-l, adapted for supplying the liquid, is a double centrifugal pump, the rotating Wheel blade or rotors 18 of which are mounted on a perpendicular .shaft 14 which is driven by means of bevel Wheels l5 by a shaft 16 which is provided With a pulley 17. The pump draus liquid from the lower part of a casing 1S and forces the same through its-guide blades 19 and rotor Wheels 13 into a collecting pas- Sage 2O from where this yliquid Hows into a passage 21, Figs. 1 and 10. This latter passage is formed in a casing 22 'which is adapted to contain the slide valve 9 and surrounds the latter Awhich comprises an inner cylinder 23 and an outeiicylinder 2l. The annular space 25 betweenboth cylinrior with the casing 18 and ,torni a dwall 30 which closes at the bottom or thib l ders is closed at at its top by an annulus 2T which is tightly adjusted on a socket 28 olthe slide valv chamber. The passage 2i is connected with the space 25 byv openings which are provided in the cylinder 2l, and the height o the passage 2l is such that this connection always exists whatever the axial position et the vslide valve 3 may be. The inner cylinder' 23 extends downward beyond thel outer cylinder 24k and passes snugly through a slide valve chamber. The proiecting en 3l of said cylinder lis formed with openings 82 which connect the space 33 which is beneath .the annular bottom wall 26 with the inside of the cylinder 23. This space is connected with the space 25 by an opening 34: formed in the bottom 26. A sieveliite cylinder is arranged in the space around the cylinder 23, this part being adapted to prevent impurities which the liquid might contain from entering the opening 3st. Un the end 3l of the slide valve 9 is mountet a bow 35 (Fig. 3) which, by means el! a ball 36 is pivoted freely on one arm ot a lever 3T, the other arm ot which is provided with a sliding balance weight 3S and is arranged in a support 39 which is on the wall 30.

The liquid which comes from the passage 21 under pressure i'ows through the openings 4t() into the space 25, from there through the sieve-like part and the opening 3e into the space 33 and passes from the latter through the openings'32 to the inside of the cylinder 23, whence it can flow into the casinglS, both through openings Lll provided in the upper part of the cylinder and out of the top of the cylinder. In order to throttle the discharge of the liquid by the slide 9, for shitting the latter, the sleeve of the distributing member can move in the inside of the end 3l of the slide in order to uncover or cover the openings 52 more or less. rthis sleeve itself is 'formed with opcnings 42 which permanently connect its intesecond outlet i'or the liquid which 'flows out` of the space l rlChe rod 8 is screwed in a block which is suspended from one end ot' the lever by moans of two thin 'steel bands T he outer cylinder 2%! of the slide is formed with two series of openings si liti, which are situated ones-.beve the ntl' rlhe oneseries l5 is adapted vte connccl space which vis i'ull oic liquid u i'idcr p with one or other oi' two openings 48 which are connected by passages wi-Vf 50 respectively with the chambers il and 52 respectively ot the operating device if.3 while the other series is arranged so that it connects an opening in the passage 50 with the casing 18 when the opcn- 'ing l? is connected by the openings e5 with its bottom by a wall 26 and l the space and. l

i z l l i i l l i b re ad th is also iixedg this lamina against the points ,te `the conical 'orin ot' these part-s 25, and also the opening -,1l-7 with the casing 18 when the opening eth0 is conner' :d by the openings -it with 'the space in order to impart continuous rotary movement to the slide valve 9 for the purpose et reducing the friction during its sliding movements, a toothed wheel 54; is mounted on the inner cylinder 23 of the slide valve. This pinion is driven by means ot' an idle wheel and a pinion 5G which is keyed to the shaft le. rhe idle wheel 55 is el" such as to remain continuously in engagement with the wheel 5l, whatever the axial position of the slide valve and the wheel ne may be. The passages 4:9 and 5() open i ci the chambers 5l and. :32 oit the iriving device which are separated trom cach other by a 'lined wall 57 and by the Y sry plaie l2. rEhe latter carries a cylindrical segment 8U, which can .move along the cylindrical inner wall of the casing and elle tight joint therewith.

The device tor preventing overregulation comprises a pinion 58 which. is iiXed on the shattot the rotary plate l27 and this'pinion engages with a. toothed sector (30 arranged on one end of the lever (il which is i'reely pivoled at. t?" on the cover 63 of the casing 18. ftne other cnd of the lever 6l is connected 'with the free end of a resilient lamina (il by inca-ns of va 'part (lo, which lamina is Fixed at its other end to a column 66 which is arranged on the cover G3. On the column (3G one end et a second re ilient lamina G7 67 is twice bent at right angles and its other end is connected .by means of a helical spring (38 wit-h the arm ot the lever T, carrying the coil l. The two laminze Gli and G7 are connected together by nic-ans oft a rod (59 both the ends of which are reduced in cross section and are threaded and carry axially' movable cones 70 of which the lamintc are pressed by means oi' thumb nuts 7l having conical projections.` as si'iown in Fig. 6. Between the cones 7G is a very strong helical spring T2 surrounding the rod of). Owing and of the oi the thumb nuts. the two bend with considerable freedom prei/ceti ons lanunte can at their junction. Vlach lamina is formed' with holes 'i'l in which the rod (59' can be l al will in order to alter the connec- A`Lwcen the laiuintc. The member G5 the lever (3l with the lamina (il a cylinder 'if-l (liigvii) which-is "i the lever til and in which a can more freely; the rod 7G of t n connected. at its tree end with lumi. :i Fi. ln this rod a channel 77 is providtai which connects the two sides ot' the piston. rif'he orilice at the upper end of the channel 'YT may be more or less uncovered oy a sleeve i8 'which is slidably adjustable to position on the rod. 76. The slide valve [i sleeve 8' back into the casing 18.

chamber, the'centrifugalpump l0, the wheel 54, idlewheel 55 and pinion 56, are arranged in the casing 18 which is intended to contaln a. liquid. In the cover 63 of this casing a recess is provided in whichthe operating device 11 is partially arranged.

The 'constructional form of the regulator `described above operates as follows: The voltagevof the installation being'normal, the

lever 7 assumes the position shown in the drawing, in which position the sleeve 8 partially covers the openings 32. The liquid supplied by the centrifugal pump 10 lowS lthrough the openings 40, 34, 32, and through thel interior. of the cylinder 23 and of the The pressure of the liquid acts on one hand upon the upper surface of the wall 26 and on the yother hand in the opposite direction upon the lower face of the wall 26 and upon the surface of the annulus 27. At the openings 32 and y34 there are two drops of pressure, the proportion of which varies with the throttling of openings 32 by the sleeve 8 the pressure in space 33 varies with said throttling. The position of the'sleeve 8 is chosen that under normal voltage the slide valve 9jcloses the chambers 51 and 52 of the `motor device Aby covering the openings 46 and 45. `When the coil 1 rises owing to a drop in the voltage of the installation, the

i v rod 8 and ,the sleeve 8 descend, the latter v uncovering the openings 32 to a greater ex:

' tent. e 'In the space 33, there is then a release vofthe full pressure so that the slide valve I9-moves downward. By this means the openings are connected with the openings 48 and the openings 46`with the opening 47 i so that the chamber receives li uid under pressure, while liquid can escape. from the chamber 51 into' the casing 18. The contact arm 4 therefore is moved in a clockwise di,-

rection.

Contact arm 4 the cylinder 74 Ais quickly drawn downward by means of the pinion 58 acting through the toothed sectorGO and the lever 61. The downward movement of the cylinder 74 causes t-he piston 7 5to also move downwardly, because the liquid contained in `the laminas 64 and by means of the rod 69,'

this downward movement of the laminae 64 is communicated to the laminse 67.- `By this means the spring 68 is slightly compressed and presses the coil l downward, that is, in

a direction which is opposite tothe first .movement of the coil. lVhen therefore the movement ofA the lever 7 does not immediately produce the necessary rise in the voltber 65- and the elastic laminae 64 it is By the rotation imparted to thewhen the rod 69 age, the devices ,consisting of the` toothed sector `6() :the lever '61, the pinion 58, the laminac 6| and 67, prevent abnormal regulation. When on the contrary, the coil 1, owing to a rise in the voltage of the installation, is more strongly attracted by the electro-magnet 3, the sleeve8 rises and throttles the passage of the liquid through the openings 32 to an even larger extent. B rthis means the openings 45 are connectedy with the opening 47 and the openings 46 with the opening 53, so that the chamber 51 of the opera-tin 'de-vice 11 receives liquid under 'pressure while liquid can flow out `of the chamber 52, the Contact arm 4 rotates in the counter clockwise-direction, in order to vproduce a reduction of the voltage. The cylinder 74 is however thereby raised and the piston 75 follows the movement, so that the free ends of the laminas 64 and-67 rise and the coil is slightly raised, in order again to revent overregulation. In both cases, the amines 64 and 67 are displaced from their normal position and 'therefore slightly bent so vhat theyexert a pressure upon the piston 75 the result being that the liquid 1n vthe cylinder 74 flows gradually through the channel 77 from one side of the piston to the other. The resilient laminas therefore after a certain time has elapsed, resume their normal4 position.

Byvarying the section of the passage 77 by means of the sleeve 78, it is possible to vary the period which the lamin take t0 resume their normal position. Further for a given displacement upward or downward of the point of connection between the memossible to vary the amount by which the I:zeil 1 is moved back, by passing the rod 69 through two corresponding holes 73, which are more or less distant from the point 'of attachment of the laminae 64 and 67 to the column 66. For example, when the rod 69 is passed through the holes 73 of the laminas 64 and 67 as shown in Fig. 6, both the ,lamin 64 and 67 are defiected to a certain 'extent and the coil 1 moved a certain dis' tance whenthe member 65 1s moved a given distance. Now if the rod 69 is placed in a corresponding hole 73 in the laminae 64 and 67, but nearer to the member 65,' the same extent of movement of the member causes a relatively greater movement of the upper part of the rod 69, and a relatively smaller movement of that part of the laminas' 67 which lies between the'rod 69 and the spring 68.v The movement of the coil, therefore, in this instance is necessarily greater than in Fig, 6. O n the other hand, if the rod 69 is passed through a corresponding pair of 'holes 73 in thelamina nearer to the support 66, the same extent of movement of the member 65 causes a relatively smaller moveis in the position shown' rio the space 9 bottom 26, 'i'. e. in the 'sure that the elilort which it Will exert upon f movable. In the will rise with. a speed ymaintained open.

`\vill'then pass troni the'room part of the lamina 67' which lies bet-Ween the rod G9 and the spring GS,A and in this instancelthe movement oit' the coil is less than when the rodiGS) is .in the position shown in Fig. 6. It is in this way that the eoaction between the member and the coil l may be varied.

' Connection between the dist/rient@ and the eleotro-iiogiictz'c balance-ils the distributor oilers a relatively considerable `niass Which would oppose the rapid movements ol' the electro-magnetic couple, the efforts necessary to overcome this inertia are borrowed from the oil under pressure. For that purpose the oil under pressure entering the distributer by the openings 40 maint-ains under pressure. As the surface oi the annulus 27, which limits the space 9`is about by halt lsmaller than the surface of the bottom 26, 'the pressure in the space 9 produces a vertical effort which tends to cause thedistributer to sink. lt' is theretore necessary for maintaining the distributer in equilibrium to produce below the space 33 such a presthe .bottom will be equal to the other eort mentioned. For that purpose the bottom 26 is provided With a small opening 34C; turther the space 33 communicates with the outside by the openings 32 ending in the central conduit, v*ings 42, on the bottom or l1 on the top. The

then from there by openopenings 32 can be opened or closed by the sleeve 81 connected by ymeans of the rod 8 to the electromagnetic balance 7. Let us suppose now that the-openings 32 are,v completely shut-by the sleeve 81 and that one maintains, for instancefby hand, the distributer imspace 33 a pressure equal to that the space 9 -vvill reign, as 9 and '33 are connected together by the opening 34 and as no oilpasses through 34, the distributer being 'motionless But then the vertical eilorty produced in the space 33 is greater than the effort in the room 9 and the distributor tends to rise. rElie distributer being now let loose,`but the openings 32 however maintained closed, the distributor according to the eiiort Which acts upon it, which depends on the size of the opening 3e. Let us no iv suppose 'on the other hand, that the openings 32 are The oil under pressure D through 3-i Vvand transform the pressure into speed which is lost aflterivard by the eddy. For passing from' 33 to the outside through the openings 32the same quantityof oil needs only a very much loiv'er pressure. rthere will be theretore sensibly the saine pressure in the inside of the space 33 as outside. The eilort produced by the oil under pressure in the room certain partial measure the sleeve until .device is exerted against prising incassa ment at the upper end of the rod 69 and a l 9 tends therefore to cause the distributer to .correspondingly greater movement in that sinlr.

lt v.vill be understood that between these tivo extreme cases in which tlievopenings 32 are completely open or shut, there exists a closing ot the openings, for vqliich the pressure in the space 33 is such that it maintains the distributer in equilibrium. And when the sleeve 81 is somewhat displaced the distributor Will displace in the saine direction and will. catch again in some the openings 32 are shut in an extent corresponding to the immobility of the distributor.

In the above described form of the apparatus, the member which stands under the influence ot the quantity to be regulated, has by its movements to move only the lightsleeve, so that the mass connected With it is reduced to a minimum. The result ot it is that the apparatus is highly sensitive.
